Hi, my wife had a tire breakdown today. So not a slow loss, but from one second to the other, without any foreign influence. The complete bikes were bought in November 2017, so they are only 5 months old. First she sent me a photo of a small damage to the wheel trim, the rim and the tire and I knew that she was driving over it somewhere. But it’s definitely not like that. Just looked at the tire and that’s what I still have Does it look like the tire on the edge has simply “dissolved” or the rubber has detached itself from the fabric? An expert here who can tell me more about it? Will this of course complain to the online retailer. It is Bridgestone Blizzark tires (the first brand tires of my life…) The “bordstone damage” is in a completely different place on the tire, the wheel trim is not scratched, but pressed in by outside. In my opinion, this damage comes from outside. so that my wife went over a lowered kerb with the plate to stop there. So in my opinion the kerb damage happened only after the actual problem and there the rubber is broken, but there is no hole, there is no air out there. It clearly escaped where to see on the photo. I am grateful for every hint.
